command expansion, the tick should slant left (<code>`</code> vs
<code>´</code>).</h1>

<span id="cb2-2"><a href="SC1077.html#cb2-2" aria-hidden="true" tabindex="-1"></a><span class="bu">echo</span> <span class="st">&quot;Your username is </span><span class="kw">`</span><span class="fu">whoami</span><span class="kw">`</span><span class="st">&quot;</span>  <span class="co"># Deprecated, will give [SC2006]</span></span></code></pre></div>
<h3 id="rationale">Rationale:</h3>
<p>In some fonts it's hard to tell ticks apart, but Bash strongly
distinguishes between backticks (grave accent <code>`</code>), forward
ticks (acute accent <code>´</code>) and regular ticks (apostrophe
<code>'</code>).</p>
<p>Backticks start command expansions, while forward ticks are literal.
To help spot bugs, ShellCheck parses backticks and forward ticks
interchangeably.</p>
<h3 id="exceptions">Exceptions</h3>
<p>If you want to write out literal forward ticks, such as fancyful
ascii quotation marks:</p>
<div class="sourceCode" id="cb3"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb3-1"><a href="SC1077.html#cb3-1" aria-hidden="true" tabindex="-1"></a><span class="bu">echo</span> <span class="st">&quot;</span><span class="kw">``</span><span class="st">Proprietary software is an injustice.´´  - Richard Stallman&quot;</span></span></code></pre></div>
<p>use single quotes instead:</p>
<div class="sourceCode" id="cb4"><pre class="sourceCode sh"><code class="sourceCode bash"><span id="cb4-1"><a href="SC1077.html#cb4-1" aria-hidden="true" tabindex="-1"></a><span class="bu">echo</span> <span class="st">&#39;``Proprietary software is an injustice.´´  - Richard Stallman&#39;</span></span></code></pre></div>
<p>To nest forward ticks in command expansion, use <code>$(..)</code>
instead of <code>`..`</code>.</p>
